WARRANTY

This product meets the current EU minimum warranty requirements, if purchased in countries of the EU. To ensure your warranty policy keep your original receipt proofing the date of purchase. Any damage to the product as a result of misuse, abuse, accident, incorrect wiring, improper installation, alteration of date code or barcode labels, revolution, natural disaster, or any sneaky stuff because someone messed up, repair or alteration out side of our factory or authorized service centers and any thing else you have done that you should not have done is not covered. This warranty is limited to defective parts and specifically excludes any incidental or consequential damages connected therewith.

IMPORTANT NOTES PRIOR TO INSTALLATION

• ATTENTION: Before you start with the installation, disconnect the ground connection from the vehicle's battery in order to prevent short circuits.
• This device is only suited for a 12 volt system in a vehicle with negative ground.
• The radiated heat while operation requires sufficient air circulation at the place of installation. The device may not be installed in small closed location or spaces without air circulation (e.g. spare wheel recess or below the vehicle carpeting). Ensure sufficient protection against vibrations, dust and dirt.
• Ensure that the input and output cables are sufficiently separated from the power supply cables.
  • Otherwise interferences may occur.
• Ensure the accessibility of the fuse and the operating elements after installation.
• The reliability and performance of the device depends on the quality of installation. Preferably consult an expert to install the system, particularly if you want to install several loudspeakers.

INSTALLATION

1. Mount the device in the car as shown below.
2. Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat belts, gastank or the like.

PROTECTION CIRCUIT

If the POWER LED (Fig. 1, 1) lits up blue, the device is in normal operation. If the PROTECT LED (Fig. 1, 1) lits up red, the device is overheated. If this events, the internal built-in protection circuit shuts down the device automatically. The device should work again properly after cooling down.

INTERCONNECTION

POWER SUPPLY AND TURN-ON-CONNECTION

The power wiring which is usually installed in on-board car networks is not sufficient for demands of this device. Make sure that the power wires to GND and to the +12 V terminal has been sufficiently specified. A cable crosssection of at least 10 mm² must be used to connect the battery to the terminals of the device.

First connect the GND terminal (Fig. 1, 13) of the device to an appropriate ground connection at the chassis. To ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion.

Then connect the +12 V terminal (Fig. 1, 12) of the device with the battery by using an appropriate cable including an in-line fuse (Fig. 1, 14). This fuse should be located very close to the battery (Fig. 1, 15); for safety reasons not more than 30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been accomplished.

Then connect the remote turn-on-wire from the head unit (Fig. 1, 11) with the device's REMOTE terminal. A cable with a cross-section of 0.5mm² is adequate.

AUDIO SIGNAL CABLES

When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the device (Fig. 1, 8), the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. We recommend a separated installation, e.g. routing the power cable through the cable channel on the left side and the audio cables through the cable channel on the right side or vice versa. This prevents interferences due to crosstalk into the audio signal.

HIGH LEVEL INPUT

The HIGH LEVEL INPUT (Fig. 1, 7) is suitable to connect the device input with speaker wires, if your head unit is not equipped with pre-amplifier RCA outputs. Extend therefore every regarding speaker cable from your head unit with appropriate speaker cables from your car audio retailer to the mounting location of the amplifier. Then connect the each matching loudspeaker cable with the cables of the included HIGH LEVEL INPUT jack like described below.

CAUTION: Never use the HIGH LEVEL INPUT and the RCA inputs at the same time. This may damage the device seriously. The loudspeaker cables of the HIGH LEVEL INPUT must have no contact to the ground (GND) by any means.

AUTO TURN ON

Push the AUTO TURN ON switch (Fig. 1, 10) to ON position. The amplifier detects now a voltage rise (6 Volts) with a so called "DC Offset" over the connected input signal on the HIGH LEVEL INPUT (Fig. 1, 8) when the head unit will be switched on. Hence, the amplifier will also be turned on. As soon as the head unit will be turned off, the amplifier turns also automatically off. In this case the turn-on connection (REM, Fig. 1, 11) is not needed.

NOTE: The Auto Turn On function usually works with 90% of all head units, because they are equipped with "High Power"-outputs. Only with a few older and still existing head units the Auto Turn On function is not working.

OPERATING ELEMENTS

INPUT SENSITIVITY

The input sensitivity can be adjusted to any head unit. Turn the volume control of your head unit to the center medium position and then adjust the input level controls (Fig. 1,5) until you have an average medium level. This setting usually provides sufficient power reserves at optimum weighted noise voltage.

VARIABLE Low pass FILTER

Set the desired crossover frequency of the low pass filter by using the controller (Fig. 1, 3). Thus to that only the frequencies below the chosen crossover frequency will be amplified and the subwoofer plays more precised and efficient.

VARIABLE BASS BOOST

By using the boost controller (Fig.1, 4) you are able to increase the bass boost level from 0 dB to 18 dB.

CAUTION: Please use the bass boost with care.

PHASE SWITCH

The PHASE-switch (Fig. 1, 2) allows to set the phase between 0° or 180° to match the run time of the output signal with the vehicle's interior acoustic.

TROUBLESHOOTING

If you are having problems after installation follow the Troubleshooting procedures below.

Procedure 1:

Check the device for proper connections.

Verify that POWER LED is on. If POWER LED is on skip to Step 3, if not continue.

1. Check the fuse of the device or the external fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal on the vehicle's chassis. Repair/replace if necessary.
3. Verify there is 9 to 16 Volts present at the positive battery and remote turn-on cable. Verify quality connections for both cables at device, head unit and battery/fuseholder. Repair/replace if necessary.

Procedure 2:

PROTECTION LED is on.

1. If the PROTECTION LED is on, this is a sign of driving the device at very high power levels without adequate air↓ow around the device. Shut off the system and allow device to cool down. Check that the vehicle charging system is maintaining proper voltage. If the previous items do not solve the problem, a fault may be in the device.

Procedure 3:

Check the device for a proper audio signal.

1. Verify good RCA input connections at head unit and device. Check entire length of cables for kinks, splices, etc. Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.

Procedure 4:

Check the device for a popping noise while turning on.

1. Disconnect input signal to device and turn device on and off.
2. If the noise is eliminated, connect the REMOTE lead of device to source unit with a delay turn-on module.

Procedure 5:

Check the device if you experience excess Engine Noise.

1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.

OR
2. Bypass any and all electrical components between the head unit and the device. Connect unit directly to input of the device. If noise goes away the unit being bypassed is the cause of the noise.

OR

1. Remove existing ground wires for all electrical components. Reground wires to different locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.

OR

1. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.
